Applied Programming Assignment
Task A:
1. In order to demonstrate your understanding of Programming within an Object Oriented visual environment you are required to design software to replace the current manual process for collecting, analysing and storing 'Step Test Data'.
2. From your research and understanding of the software analysis and design process produce the necessary design documentation to define and model your solution.
Guidance:
Your tutor will act as the customer and as such, will be available for interview during class / lab sessions. However, the document used for recording the current manual process is given below which includes the following instructions for the graphical analysis:
1. Plot the heart rate at each of the levels until they achieve approximately 85% of their max HR. Nb. ensure the levels correspond to the correct step height.
2. Draw a straight line that best fits these points.
3. Extend this line to cross their max HR line for their age.
4. Drop a line from this intersection to the baseline and read the predicted aerobic capacity (units mls02/kg/min)
Additional customer notes and observations (often vague and undefined):
- The test may be performed by a single individual but equally, the test could be applied to a group of participants. The participants details can be entered manually before each test or the list of participant details can be imported prior to the test session taking place. In this case, the operator will select a participant before each test.
- The step height can differ but it is specified and fixed for any particular testing session.
- Once the parameters have been defined and set for each test the participant will commence the first step test. On completion, the first heart rate reading will be taken and recorded.
- Any recorded HR less than 50% of the maximum HR will be ignored in the final calculation.
- The participant will then continue this process up to a maximum of FIVE tests or until the HR reading is above 85% of the max HR.
- Any recorded HR greater than 85% of the maximum HR will conclude the test but will be ignored in the final calculation.
- Once the reading exceeds 85% the testing is over for the current participant.
- Currently the paper documents are filed for reference so the data and results for each test will need to be stored in a persistent database. Users should be able to switch to a different screen to query previous test data of the current participant.
- Once an individual participant has completed the test the system will need to reset ready for the next participant.
- The system will need to deal with special cases, i.e. If there's no - or only one - valid reading
Assessment:
To obtain a 'C' all the criteria listed must be achieved. Higher grades will be given for work of higher quality. For example a 'B' - 'B+' for work of high quality in some areas and a 'A' for work of high quality in all or most areas.
Quality will be demonstrated by the following:
1. Creativity and adaptability
2. Showing synthesis of concepts
3. Breadth and depth of the solution design
4. Autonomy and independence
5. Coherence of design
6. Extent of exploitation of the GUI
